USDCLP long term relationship SPY

as we can seen is a kind of relationship waiting ( is not perfect of course a like all the relations cheap ) the SP and the currency of the latin countries ( for that sample we put it the pair : USD/ CLP chilean money )
So. every time the SP is an upward trend for a long term (several years) the Latin currencies are desfavorecidad VS the USdollar , and in turn it can be observed when the SP has a bearish trend , Then the synchronization efect is it not perfect at all, but the effect it is clear in the long time.
